Breast cancer in women: evaluation of benign and malignant axillary lymph nodes with contrast-enhanced ultrasound

PURPOSE

We assessed the value of contrast-enhanced US for differentiating between benign and malignant axillary lymph nodes in breast cancer.

MATERIALS AND METHODS

A total of 120 axillary lymph nodes in 92 patients with breast cancer were studied. All patients underwent grayscale US examination, unenhanced and enhanced color and power Doppler US, and enhanced grayscale harmonic US examination.

RESULTS

The mean size of the 120 axillary lymph nodes was 1.5 cm (range 0.5 - 3.4 cm). Of all 120 axillary lymph nodes studied, 80 (67 %) were malignant and 40 (33 %) were benign according to pathological examination. The total number of vessels in baseline US did not increase between benign and malignant lymph nodes (3.3 +/- 2.2 vs. 5.4 +/- 4.0; p > 0.05). The total number of peripheral vessels was 0.5 +/- 0.8 for benign lymph nodes vs. 2.0 +/- 1.7 for malignant lymph nodes (p > 0.05). Enhanced US studies showed enhancement in both benign and malignant lymph nodes after contrast administration with a significantly higher degree of enhancement in malignant lymph nodes (p < 0.01). The total number of vessels was significantly higher in malignant lymph nodes after contrast administration (17.3 +/- 8.0 vs. 8.2 +/- 5.1, p < 0.01). Malignant lymph nodes demonstrated longer contrast enhancement duration compared to benign lymph nodes.

CONCLUSION

This preliminary data shows that contrast-enhanced US can differentiate between benign and malignant lymph nodes in breast cancer.

Cervical cancer associated with genital prolapse--a brief review of the literature and long-term results of successful treatment with radiochemotherapy and surgery in a very frail patient

BACKGROUND

A case of cervical cancer associated with irreducible procidentia successfully treated with external beam radiation and extracorporeal HDR-AL with concomitant chemotherapy followed by obliterative vaginal surgery is reported for the first time.

CASE

A 73-year-old woman presented in frail condition suffering from a huge, irreducible uterovaginal procidentia combined with a squamous cell carcinoma of the cervix in FIGO Stage IIa. Successful treatment consisted of sequential application of combined radiotherapy with concurrent cisplatin chemotherapy followed by total vaginal hysterectomy and partial colpectomy with colpocleisis according to the Labhardt method. The five-year follow-up documents the excellent long-term results with regard to cervical cancer and pelvic floor stability.

CONCLUSION

Especially in patients ineligible for extended surgery, radiochemotherapy followed by an obliterative surgical approach is feasible without aberrant wound healing and constitutes a suitable and efficient option for treating carcinomas of the cervix associated with irreducible genital prolapse.
